Abstract
A method and apparatus for a light emitting devices based display have been disclosed.
Claims
exact text as granted — not AI-modified1 . A method comprising:
(a) positioning an array of light emitting devices (LEDs) in a first position; (b) moving said array of LEDs; (c) determining if said array of LEDs are in a given position; (d) receiving an input display signal; (e) energizing one or more LEDs in said array of LEDs; (f) sensing if said array of LEDs is at an end position; and (g) if not at said end position repeating (b) through (f); and
if at said end position repeating (a) through (f).
2 . The method of claim 1 wherein said positioning and moving further comprises a linear motion.
3 . The method of claim 1 wherein said energizing is based upon said received input display signal;
4 . The method of claim 1 wherein said array further comprises an array of substantially red light emitting diodes, an array of substantially green light emitting diodes, and an array of substantially blue light emitting diodes.
5 . The method of claim 4 further comprising focusing any light emitted from said red, green, and blue light emitting diodes on a projection surface.
6 . The method of claim 1 further comprising M said light emitting devices and N said given positions and said method of claim 1 is capable of producing an M×N display.
7 . A machine-readable medium having stored thereon instructions, which when executed performs the method of claim 1 .
8 . A system comprising a processor coupled to a memory, which when executing a set of instructions performs the method of claim 1 .
9 . The method of claim 1 further comprising communicating a payment and/or credit.
10 . An apparatus comprising:
a linear movement stage; a substrate mounted to said linear movement stage; an array of light emitting devices (LEDs) attached to said substrate; and a controller attached to said substrate.
11 . The apparatus of claim 10 wherein said linear movement stage is capable of movement in one or more directions.
12 . The apparatus of claim 10 wherein said linear movement stage is capable of movement back and forth.
13 . The apparatus of claim 10 wherein said controller is coupled to control illumination of zero or more LEDs of said array of LEDs.
14 . The apparatus of claim 13 wherein said controller is coupled to control positioning of said linear movement stage.
15 . The apparatus of claim 10 wherein said linear movement stage further comprises one or more substantially parallel rails.
16 . An apparatus for creating a display comprising:
means for positioning an array of light emitting devices (LEDs); means for energizing zero or more LEDs of said array of LEDs; and means for focusing any light from said energized zero or more LEDs.
17 . The apparatus of claim 16 further comprising means for compensating for wear associated with said LEDs.
18 . The apparatus of claim 16 further comprising means for compensating for wear associated with said means for positioning.
19 . The apparatus of claim 16 wherein said means for positioning comprises means for positioning in a substantially circular path.
20 . The apparatus of claim 16 further comprising means for producing an M×N display using M LEDs in said array of LEDs and N positions.
21 . The apparatus of claim 16 further comprising means for producing an M×N display using M/2 LEDs in said array of LEDs and N positions.
22 . The apparatus of claim 16 further comprising means for producing an M×N display using M/J LEDs in said array of LEDs and N positions where J is an integer greater than zero.
23 . The apparatus of claim 20 further comprising creating said M×N display substantially 24 to 170 times per second.
24 . A machine-readable medium having stored thereon information representing the apparatus of claim 16 .
25 . An apparatus comprising:
a first linear movement stage mounted on one or more rails oriented in a first direction; a platform mounted to said first linear movement stage; a second linear movement stage mounted on one or more rails oriented in a second direction attached to said platform; a substrate mounted to said second linear movement stage; and an array of light emitting devices (LEDs) attached to said substrate.
26 . The apparatus of claim 25 wherein said first direction and said second direction are substantially at a right angle.
27 . The apparatus of claim 25 further comprising:
a first moving means attached to said first linear movement stage; and a second moving means attached to said second linear movement stage.
28 . The apparatus of claim 27 wherein said second moving means is mounted on said platform.
29 . The apparatus of claim 25 further comprising one or more lenses in optical communication with said array of LEDs.
30 . A system for displaying an image comprising:
means for receiving a display signal; means for positioning an array of light emitting devices (LEDs); means for determining a precise location of said array of LEDs; means for energizing one or more LEDs of said array of LEDs based upon said display signal; and means for optically conveying light from said energized one or more LEDs.
31 . A display apparatus comprising:
a plurality of movable optical sources capable of producing an optical output; a lens capable of receiving and projecting the optical output.
32 . The display apparatus of claim 31 where said lens further comprises a plurality of lenses.
33 . The display apparatus of claim 32 wherein some of said plurality of lenses is a group of microlenses in substantially close physical proximity to and optically coupled to one or more of said plurality of movable optical sources.
34 . The display apparatus of claim 33 wherein some of said plurality of lenses are lenses associated with a projection lens system for projecting said optical output onto a viewable surface.
35 . The display apparatus of claim 34 wherein said viewable surface is selected from the group consisting of a flat surface, a retinal surface, and a semi-transparent optical surface.
36 . A method for producing an M×N display, the method comprising:
moving a row of substantially linearly spaced M elements capable of light production to N positions; and energizing one or more of said M elements to produce said light production at one or more of said N positions.
37 . A method for producing an M×N display, the method comprising:
moving M elements capable of light production to N positions; and energizing one or more of said M elements to produce said light production at one or more of said N positions.
